Rainbird XFD on‑surface Dripline

Rainbird XF pressure-compensating dripline, Rain Bird code X44222.

Brown coloured dripline tube, 100 metre roll.

The Tube is 17mm diameter and requires 17mm Dripline fittings. Please note that normal garden fittings will not work on this tube.

Emitters are spaced 50cm apart along the wall of the tube.

Flow rate per drip emitter 2.3 litres per hour.

This is the Dark Brown dripline that many irrigation contractors prefer to use. Drippers are 50 cm apart, each dripper has a flow rate of 2.3 litres per hour.

Dripline comes in a coil and looks like normal (brown) poly tube. If you look closely though you’ll see a “knuckle” extruded inside the tube every 50cm, and a tiny hole about a millimetre across. The knuckle is a pressure-compensating labyrinth and the tiny hole is where the water emerges from.

Our Rain Bird dripline is pressure compensating (PC), meaning that every drip emitter down the coil will only emit exactly the specified amount of water (2.3 litres per hour for this model), regardless of the pressure inside the pipe, or whether it’s at the start of the coil or at the far end, which could be as much as 100 metres away!
